Automotive lumbar support systems have demanding leak test requirements due to their application – customers of high-end vehicles will not tolerate a deflated seat!

We were able to partner with a tooling integrator to meet a customer’s specific needs – testing multiple lumber support bladders over two tooling faces to deliver highly sensitive and accurate low pressure testing; whilst driving throughput improvements.

Two independent stations are loaded with 8 bladders. These are filled to the pressure prescribed in the leak test programs – typically 7 psi – and stabilised in parallel. Each unit is then leak tested using the FCO750 pressure decay leak tester.

Each tooling position has a R/A/G LED driven from the outputs of the FCO750; mimicking the display on the front of the FCS456. The operator can quickly ascertain whether a part has passed or failed the test. This facilitates fast load and unload times; in combination with a second bank of test envelops. The two test banks of 8 test envelopes are switched by a PLC driving 8 of our leak proof air-piloted M1143 change-over valves. This facilitates greater use of the operators time, driving faster testing and more efficient use of the FCO750.

The pass and fail rate of these parts are stored in the FCO750’s large internal memory for later analysis; and the machine status is monitored by a factory OEE data collection system for real-time machine status.

Fuel Line Testing

Manufacturers trust Furness Controls to provide a range of solutions to suit their needs, from the fully comprehensive to the most economical giving our customer confidence in their processes along with our expertise the backup they rely on. The methods we employ combine air pressure of flow to check for blockage and pressure decay to test for leaks. We can accommodate pressure from high vacuum to 30 Bar within a single instrument.
